b.
Use conversion factor in formula:
amount of ingredient
amount of each
Conversion factor X
in official formula
=
ingredient needed
c. Sample Problem: Use the official formula below to calculate how much of
each ingredient would be needed to make 120 ml of Cocoa Syrup.
Cocoa Syrup
Cocoa......................................................
180 g
Sucrose...................................................
600 g
Liquid glucose..........................................
180 ml
Glycerin...................................................
50 ml
Sodium chloride..........................................
2g
Vanillin...................................................
0.2 g
Sodium benzoate.......................................
1g
Pure water
.........
qsad ......
1000 ml
(1)
The first step is to find the conversion factor:
120 ml
= conversion factor
1,000 ml
NOTE:
The units, by being the same, cancel.
0.12
= conversion factor
(2)
The second step is to multiply the conversion factor times the amount
of each ingredient in the original formula:
Conversion
Amount of Ingredient
Amount of Each
=
Ingredient Needed
